Use WordPress to print a RSS feed for Eventbrite attendees
Today I was working on the WordCamp.LA site. I was trying to show the “attendee list” on the attendees page with out having to update the page every day.
Since I am using EventBrite to promote and sell ticket to the event I can collect info from there list. Evey one who purchases a ticket gets put into the ticketed database which you can view with either RSS or OPML.
I chose to use RSS and the WordPress core file rss.php
.
In the functions.php file I’ve added this function:
function attendee_feed_print_2009() { global $wpdb; include_once( ABSPATH . WPINC . '/rss.php' ); $rss = fetch_rss( 'http://www.eventbrite.com/rss/event_list_attendees/384870157' ); $items = array_slice( $rss->items, 0 );
Where I’ve named my function, and included the core RSS file from WordPress. I also told it to fetch the feed from the address (alternatively you can use any feed link you like).
if ( empty( $items ) ) echo '<ul style="list-style-type: none; list-style-image: none; list-style-position: outside;"><li>No items</li></ul>'; else foreach ( $items as $item ) : ?> <ul style="list-style-type:none; list-style-image:none; list-style-position:outside; margin-bottom: 0px"> <li><!--<strong><?php echo $item[ 'title' ]; //User name ?></strong><br />--> <?php echo $item[ 'content' ][ 'encoded' ]; ?> <hr style="border: 1px solid #ddd; margin-bottom: 8px" /> </li> </ul> <?php endforeach;
I then added the core style to fit this current feed.
And the final out come looks like this:
function attendee_feed_print_2009() { global $wpdb; include_once( ABSPATH . WPINC . '/rss.php' ); $rss = fetch_rss( 'http://www.eventbrite.com/rss/event_list_attendees/384870157' ); $items = array_slice( $rss->items, 0 ); if ( empty( $items ) ) echo '<ul style="list-style-type: none; list-style-image: none; list-style-position: outside;"><li>No items</li></ul>'; else foreach ( $items as $item ) : ?> <ul style="list-style-type:none; list-style-image:none; list-style-position:outside; margin-bottom: 0px"> <li><!--<strong><?php echo $item[ 'title' ]; //User name ?></strong><br />--> <?php echo $item[ 'content' ][ 'encoded' ]; ?> <hr style="border: 1px solid #ddd; margin-bottom: 8px" /> </li> </ul> <?php endforeach; }
Don’t forget to wrap the code in <?php
?>
I want to thank John Kolbert for helping me with printing the content:encoded
portion. http://pastebin.com/m1588fb30

Tips & Tricks
Can′t add pagination on WooThemes Thick Theme
Everything I have tried has led to nothing. And I have tried six way’s from Sunday to get my main posts to paginate.
example one:
<?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; query_posts('offset=1&showposts=' . get_option('woo_other_entries') . '&cat=-' . $GLOBALS['ex_asides'] . '&paged=$paged' ); ?>
example two:
<?php global $myOffset; global $wp_query; $myOffset = 1; $paged = intval(get_query_var('paged')) ? get_query_var('paged') : 1; $temp = $wp_query; $wp_query= null; $wp_query = new WP_Query(); $wp_query->query(array( 'offset' => $myOffset, 'category__not_in' => array($GLOBALS['ex_asides'],7,84), 'paged' => $paged, 'showposts' => get_option('woo_other_entries'), )); ?>
example three:
<?php global $myOffset; $myOffset = 1; $wp_query = new WP_Query(); $wp_query->query(array( 'offset' => $myOffset, 'category__not_in' => array($GLOBALS['ex_asides'],7,84), 'paged' => $paged, 'showposts' => get_option('woo_other_entries'), )); ?>
And after those tries, I just can’t get more pages beyond the option’s that I choose, and can only pull an archive via the browse more link.
Any suggestions or anything?
Tips & Tricks
Pulling custom fields from outside the loop
In the last post “Creating a custom widget” I showed you how to create a custom widget. Well in this post I will show you how I used my custom widget to display all post with a certain custom field from outside the WordPress loop.
In the last post I used this tag:
<?php include(TEMPLATEPATH . '/includes/showcase.php'); ?>
Now I will show you what the file showcase.php
has:
<ul> <?php global $wpdb; $sql = "SELECT wposts.* FROM $wpdb->posts wposts, $wpdb->postmeta wpostmeta WHERE wposts.ID = wpostmeta.post_id AND wpostmeta.meta_key = 'gallery-url' AND wposts.post_status = 'publish' AND wposts.post_type = 'post' ORDER BY wposts.post_date DESC LIMIT 8"; $pageposts = $wpdb->get_results($sql, OBJECT); $output = $pre_HTML; foreach ($pageposts as $post) : setup_postdata($post); ?> <li><a href="<?php echo get_post_meta($post->ID, "gallery-url", $single = true); ?>" title="Link to <?php the_title(); ?>"> <img src="<?php echo get_post_meta($post->ID, "image", $single = true); ?>" alt="<?php the_title(); ?>" /></a></li> <?php endforeach; ?> </ul>
That’s it! The most important item you may want to change for your own custom field is the line : AND wpostmeta.meta_key = 'gallery-url'
. Where you would change the text in bold to match your own custom field value.
Update:
Check out Austin from PressedWords comment below.
With his great advise I was able to figure out why all my attempts to use the query_post weren’t working. it came down to this line of code: <?php echo get_post_meta($post->ID, "gallery-url", $single = true); ?>
, that was what I had in my code, and the $post->ID
is the reason my code would not echo or print the custom field’s value. Solution? replace $post->ID
with get_the_ID()
. HA, so simple.

Creating a custom widget
Today let’s learn a simple quick trick on how to create a custom widget. For my example I will show you how I created my Showcase widget located in the middle, to the right of the posts.
First under your functions.php
file type in the following:
<?php // Custom Widget function MyCustomWidget() { ?> <li class="widget"> <h2 class="heading">Latest Showcase</h2> <ul> <?php include(TEMPLATEPATH . '/includes/showcase.php'); ?> </ul> </li> <?php } register_sidebar_widget('The Custom Widget for Showcase', 'MyCustomWidget'); ?>
- Always make sure your code is between the
<?php
and?>
for it to work. - Once we call the function, the rest is assuming html code that you may or may not need.
- For instance, you may just put in a picture and call it a day. But my code starts with
<li<
because my sidebar’s start and end with<ul<
. - Any way, once your done, just set the final “
register_sidebar_widget('the widget title', 'the name of the function');
“
That’s it! Now you have a custom widget with what ever you want!
